Torque constant limit（positive）
Constant-power torque limit
Constant-power torque limit
Constant-power zone
Torque constant limit（negative）
Note: When certain toque limit is selected (F6113=1), since there is no possible of overload in constant-power zone, the
certain torque output limit must be set (F6113=0).
Reference parameter
F5001（Motor poles, voltage and capacity）。
F5004（Motor speed rating）。
F6114 Speed limit selection
F6115 Speed limit value in torque control (Forward run side)
F6116 Speed limit value in torque control (Reverse run side)
The function to set speed limit value in torque control mode (speed sensored and speed sensorless).
Code No. Function Name
F6114 Speed limit selection
F6115 Speed limit value in torque control
(Forward run side)
F6116 Speed limit value in torque control
(Reverse run side)
● Carry out torque control within the speed range set by this function.
● When speed limit value is exceeded, switch the speed control using speed limit value as the command.
● When using F6114=0:1 speed frequency command to set the speed control, the synchronized speed operated from 1
frequency command will be used for speed control. In this case, the values should be set according to the settings of 1
frequency setting selection (F1002).
Example) When the speed limit value is set within the scope of 0-5V with the external analog VIF3 input,
Speed limit selection: F6114=0.
st
1 speed frequency setting selection: F1002=6.
● When speed limit in function codes (F6114=1) is set, the speed limit value in torque control (forward run side) (F6115) and speed
limit value in torque control (reverse run side) (F6116) will be used for speed control. With the default values, the setting of
using function codes is effective. The speed limit values in forward run and reverse run can be set separately. Also, when fixed
speed limit value is required from the startup, please select the settings described here.
Example When speed control value in forward run side is 1500rpm and the speed control value in reverse run side is -1000rpm,
Speed limit selection: F6114=1.
Setting of speed control value: F6115=1500rpm, F6116=1000rpm.
